ATTORNEYS Patented Sept. 29, 1931 MAX KAPPNER, OF CINCINNATI, OHIO ARCHSUPPORT ADJUSTER Application iiiea riuy a, i929. seriai Np. 375,835.

My invention relates to improvements in devices foraltering theconfiguration of arch supportsand is particularly adapted for use inconnection" with'V arch supports for the hilmanfootmade in accordancewith Vthe teachings of'Lett'ers Patent of the United States 1,395,498issued to me November' 1, `1921.`v

It will be understood that malformations of the foot vary so greatlythat each foot fitted is apt to present an individual problem requiringsome special rchange of the configuration of the metal portion of thesupport. The purpose of my presentV invention is to provide a device'capable'of making all kinds of such changes and to a slight orsubstantial degree as the particular foot to be fitted requires. H

` Another object of my invention is to enable greater pressure to bebrought upon the forward 'or rearward orv upon the -inside or outside ofthe support as needed, instead of Va uniform pressure Therefore, Iprovide fmeans 'for adjusting the position of the pressure block so asyto secure such special pressure or pressures instead of the uniformpressure.

vAnother object of my invention ist yprovide a device in which the leverin either using 30 `or n'omusing position is completelyout of `the way,where it will not interfere with those passing the benchto which the'device is secured.V v Devices for this general' purpose 7 heretoforemade have' been so generally protruding from the bench as tobe likely toinjure those passing orbe itself broken 'of:l

c Another object of my' invention is `to 'pro- 7 vide an' anvil tabletop on the device which together 'with' thefpressiire'block providesmeans for making every change or alteration necessary ltobe made on anarch support. c I also'provideia specially'forined hammer fortaking'vc'are of all thefvarious uses to which the` deviceiis to be put,aside from the changes made by pressure delivered through the pressureblock.

-f y In the particular embodiment'of my invention selected forillustration Figure Y1 is a vertical.sectionfthrough the provided on thehandle device, the device being working bench,

Fig. 4 is a plan view of porty adapted to conform t every bone in thefoot, and

shown secured to a F 1g` 2 is a. top plan view ofthe device,

Referring now to ticularly Figs. 1, 2 and 3 the drawings and pai'-,

, the device is secured to any suitable work table or bench 6 by meansof screws able manner. cured between tain'the vise in open position as 7or in any other suit- The double arm vise 8 is sethe base 9 and anvil 10by means of thumb screws 11, member being free to reciprocate on 9. Arod 12 threaded at bothl its ends is sei cured at one end -13 to theanvil tabletop table top. 5

tion of the handle so that with the. bench or table is secured.

A metal pressure block .'ioned is adapted to have lated bythumb setscrews varied directions. provided 'on its top 8, and on" 9 adapted tobear of the anvil table A boss or stp '32 is 17 to limit the rotait willnot contactr 80 to 'which the device 20 suitably cushits position regu-2i, 22, 23 and 24...'.

The pressure block 20 may be made as a singlepiece :or may be splitcentrally or otherwise so as to have pressure exerted in more The anviltable top 10 is surface with an embossnient 'centrally depres arch sedin which the may be adjusted toV 'conform tothe particular curvatures ofthe cuboid and'scaph- The table top is er embossinent 26 n which thearch may bev adjusted to conform to the curvature of the metatarsalbones.

\ provided with apertures which the spur of the arch The table top is'27 and 28 upon is placed'so as not 100 to injure the spur in loweringthe arch. A rounded flange 29 on the anvil table top is provided with avertical aperture 30 through which rivets may be driven out of the archsupport and the longitudinal aperture 31 is provided therethrough sothat the rivets may be taken out of the flange.

In order to change the configuration and curvature of the arch 33, it isplaced between the pressure block and the face 34 of the anvil table topwith the metal portion of the arch in contact with the pressure block.The face 34 is formed to prevent flattening of the metatarsal portion ofthe arch support when pressure is applied. Any of the set screws Q1, 22,23 and 24 are then adjusted as desired, and the operating` handle 17 israised to whatever height is desired in order to bring pressure upon thearch 33 to increase the curvature of the arch support. vWhen the handle17 is in its extreme upper position it becomes locked there due to thethen position of the cam 19 as shown in Fig. 1.

In order to flatten or lessen the curvature of the arch 33, it is laidupon the anvil table top with the spur 36 over one of the apertures 27or 2S and the hammer 37 is used to apply whatever force is necessary tolower the arch support. This hammer 37 has any suitable handle 38 andhas a metal tube member 39 to rigidly secure the raw hide heads 10 and41 to the handle, the head 40 being flat and the head 41 being rounded.In order to change the curvature of the flange 12 of the arch support toconform to the particular curvature of the scaphoid bone and instep, theflange is laid upon the rounded flange 29 on the anvil table top withthe metal portion up and the flat end 41 of the hammer is used to changethe curvature of the flange 42. If it is desired to remove a rivet fromthe arch support, the rivet is laid over the aperture 30 and removed bytapping the rivet with the hammer 37 and any suitable punch. In order tochange the arch support to conform to the curvature of the metatarsal,the arch support is laid over the embossment Q6 and the rounded end 41of the hammer used to give the necessary pressure. If the arch supportis to be changed to conform to the curvature of the cuboid and scaphoidbones, it is laid upon the embossment 25 and the rounded end of thehammer used to make the change. i
